FBH To Show Latest Technology At Laser World Of Photonics


FBH will show live demonstrators for LiDAR and Raman spectroscopy and advances in laser diodes and UV LEDs

The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) is showing its range of services at Laser World of Photonics in Munich from June 24-27, 2019. At the joint Berlin-Brandenburg stand, the institute will present current developments, from chips and modules with and without fibre coupling to live demonstrators. At the accompanying CLEO conference, FBH will be represented with 16 scientific contributions.

LiDAR demonstrator: stand-alone, PC-controlled pulsed laser source

As part of 'Research Fab Microelectronics Germany', FBH is presenting a live demonstrator for pulsed laser sources, which allows flexible adjustment of pulse duration and intensity. Visitors can use a tablet to change the desired parameters and monitor the results in real time on screen.

With its PLS flex, FBH offers laser sources that deliver pulses in the range from 200 ps to 20 ns. The systems can be equipped with diode lasers of various wavelengths (630 - 1180 nm) and power ranges. Laser diodes, which are wavelength stabilised at 905 nm, achieve output powers of up to 100 W at ambient temperatures of up to 85degC. This makes them suited for use in LiDAR systems. FBH offers the chips in a complete development environment with driver electronics and control software.

SERDS turnkey system in use - for Raman spectroscopic measurements on site

The compact turnkey laser system for Raman measurements is equipped with a monolithic Y-dual-wavelength diode laser, which alternately emits light at two slightly different wavelengths. The system allows very fast measurements using Shifted Excitation Raman Difference Spectroscopy (SERDS). The spectral distance of both wavelengths can be adjusted via micro heaters above the DBR gratings, which define the wavelength. If the systems are complemented with a suitable power supply, spectrometer, data acquisition and software interface, they can be used for on-site measurements. In-house developed, portable systems have already been successfully used for measurements on food, soil, plants and human skin.

AngelTech Online Summit - Tuesday 19th May

The health and well-being of AngelTech speakers, partners, employees and the overall community is our top priority. Due to the growing concern around the coronavirus (COVID-19), and in alignment with the best practices laid out by the CDC, WHO and other relevant entities, AngelTech decided to postpone the live Brussels event to 16th - 18th November 2020.

In the interim, we believe it is still important to connect the community and we want to do this via an online summit, taking place live on Tuesday May 19th at 12:00 GMT and content available for 12 months on demand. This will not replace the live event (we believe live face to face interaction, learning and networking can never be fully replaced by a virtual summit), it will supplement the event, add value for key players and bring the community together – digitally.

The event will involve 4 breakout sessions for CS International, PIC International, Sensors International and PIC Pilot Lines.

Key elements of the online summit:

  • Covering key topics of the industries
  • Live 3 hour online summit
  • 10 minute presentations – learn from experts in the industry
  • Recorded product demos
  • Live audience questions
  • Enhanced discussion and audience interaction
  • Video panel sessions
  • Sponsors digital booth (intro video, company content, lead generator, facilitate one on one video meetings with attendees)
  • Live private video meetings between two or more attendees
  • After the live event, monthly keynotes to drive traffic to the event 24/7, 365

Innovation is in AngelTech’s DNA and we are leveraging this strength to bring you an immersive and inspiring online event without the risk of travel during this uncertain period.
